Abstract :
Background. Quality gaps exist in the diagnostic evaluation of lung cancer patients. +e initial CT chest guides the workup of
patients with suspected lung cancer. We sought to determine how frequently CT reports provided guideline-concordant recommendations with regard to additional imaging studies and/or invasive diagnostic procedures. Methods. +is was a retrospective
study. +e records of patients referred for investigation of suspected lung cancer between January 1, 2015, and June 30, 2016, were
reviewed. Patients with confirmed lung cancer, for whom CTscan images and reports were available, are included. CTreports were
reviewed, with attention to additional imaging studies and/or invasive diagnostic procedures suggested. +ese recommendations
were examined against current guidelines for lung cancer diagnosis and staging, based on suspected disease stage. Results. One
hundred forty-six patients are included in the analysis. Most patients were diagnosed with non-small-cell lung cancer (NSCLC),
and 63% had advanced disease (stages III and IV). Only 12% of CT reports contained guideline-concordant recommendations for
additional imaging studies, with PET scan suggested in only 6% of reports. Potential invasive diagnostic procedures were
suggested in one fifth of CT reports, and only 58% of these recommendations were in keeping with current guidelines. In
particular, transthoracic needle aspiration (TTNA) was suggested in 26% of patients despite advanced stage disease. Conclusion.
Guideline-concordant recommendations for investigation of suspected lung cancer are rarely available on CT reports. +is is true
with respect to both imaging studies and invasive diagnostic procedures. Incorporation of more evidence-based suggestions may
reduce quality gaps in lung cancer diagnosis and staging.
